First, an overview 
 HDGC3510 power quality analyzer is a specialized hand-held instrument for testing the quality of grid operation and analysis. Harmonic analysis and the analysis of single-phase power quality data analysis with PC application software, and upload the collected data to a computer to facilitate a variety of analysis to determine the grid is a safe operation. 

 Second, the design features 
 A modular design, running and reliable, measurement data is fully and accurately show the operation of the voltage, current waveform. 
 2, powerful, and can be a number of professional tests and stored in the instrument, in order to view or transmitted to a computer for analysis. 
 3, pure design, Chinese operation interface, the operating habits of the Chinese people, friendly interface, and English operating system for when necessary. 
 4, using the latest line programmable CPU, users can use the computer to update the instrument software and improve instrument performance. 
 5, the total harmonic distortion (THD), up to 50 harmonics and harmonic phase angle. 
 6, prolonged monitoring, continuous measurement of voltage, current, power, and power factor. 
 7, starting the measurement, measurable, high-power load to start or stop the impact on power. 

 Third, the function 
 l, the basic parameters of measurement 
 The basic measurements show that the basic parameters of the voltage rms, current rms, and frequency and voltage and current measurement waveforms. Measurement of the DC measurement source for the average. 
 2, single-phase power measurement 
 Single-phase power measurements show that the apparent power, active power, reactive power, power factor DC measurement source measurement for DC power 
 3, three-phase power measurement 
 Three-phase power measurement shows a three-phase three-wire balanced load apparent power, power factor 
 4, the grid harmonic measurement 
 Grid harmonic measurement is divided into voltage harmonics, current harmonics, harmonic measurement, the main display 1 to 50 harmonic situation, you can display the number of harmonic (or fundamental) harmonics True RMS, harmonics contain rate (HR), total harmonic distortion (THD) of parameters and all the harmonics of the histogram. 
 5, digital oscilloscope function 
 Oscilloscope measurement of voltage and current waveforms, run to maintain (ie, manual capture), trigger (ie, automatically capture) three modes of operation.
